Thanks David. Out of interest, how does GUE calculate deco gas requirements for the T1 dives? I notice DecoPlanner spits out something in the range of 930 litres of EAN50 needed after 25mins at 45m with 21/35. Of course, this would assume you don't feel like giving your buddy any gas

Just as we calculate any gas requirement.
SAC rate X ATA X time
e.g.
let's say you have 25 min deco from 70' to surface.
let's say your SAC rate is .5
average ATA would be 2
2X .5 X 25 = 25cf of gas needed
